Equivalent expressions to 10x-4x+7x
Answer:
13x I think I could be wrong if there are answer choices look at them and make sure.
Step-by-step explanation:
Combine any like terms on each side of the equation: x-terms with x-terms and constants with constants. Arrange the terms in the same order, usually x-term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.

(2x+5)(3x−4)
Answer:
[tex]\boxed {\boxed {\sf 6x^2+7x-20}}}[/tex]
Step-by-step explanation:
We are given 2 binomials (meaning they have 2 terms) and asked to express as a trinomial.
To do this, we have to multiply the 2 binomials using the FOIL method. FOIL stands for first, outside, inside, and last. Basically, multiply the first terms from both, then the outside, and so on.
F : First
[tex](\underline{2x}+5)(\underline{3x}-4)[/tex]
2x * 3x= 6x²
O: Outside
[tex](\underline{2x}+5)(3x \underline {-4})[/tex]
2x * -4 = -8x
I: Inside
[tex](2x+\underline5)(\underline{3x}-4)[/tex]
5 *3x=15x
L: Last
[tex](2x+\underline5)(3x\underline{-4})[/tex]
5*-4= -20
Now, put all the products together into one expression.
[tex]6x^2-8x+15x-20[/tex]
However, this is not a trinomial yet. There are like terms that can be combined. Notice how 2 terms both have the variable x. They can be added together.
[tex]6x^2 + (-8x+15x)-20[/tex]
[tex]6x^2+7x-20[/tex]
Now there are 3 terms and we have a trinomial: 6x²+7x-20

Which value from the set { 1/2 , 2/3 , 4/3 , 5/2 } is a value of x that will make the equation 3/4 ÷ x = 9/8 true?
Answer:
2/3
Step-by-step explanation:
To find out what x is in this case, divide 3/4 by 9/8.
3/4 / 9/8
Dividing by a fraction is the same as multiplying it's inverse.
3/4 * 8/9
Cross cancellation (3 & 9 (GCF: 3); 4 & 8 (GCF: 4)
1/1 * 2/3
We can remove the 1/1.
2/3
2/3 is the value of x that will make 3/4 ÷ x = 9/8 true.

Answer:
144, 36
Step-by-step explanation:
you know that if you add the two angles it will equal 180 degrees. so add the two angles and make them equal to 180 and solve for x.
(4x+8) + (x+2)=180
5x+10=180
5x=180-10
5x=170
x=34
now replace x in each equation:
4(34)+8=144
34+2=36
Subtract
(5x^2-8x+7)-(2x^3+3x+1)
5x^2-11x-2x^3+6
Simplify the expression
answer: = -2x^2+6x+4
Aiden has his two friends order a pizza with 12 slices together they ate 2/3 of the pizza if they evenly divided what was left how many slices will each of them receive?
Answer: 1 1/3
Step-by-step explanation: 12/3 is 4, so if there are 4 slices remaining (since they ate 2/3 already). Dividing the remaining 4 among them means each person gets 1 1/3 of the remaining 4 slices
EVALUARE CLASA A 6A APOARTE SI PROPORTII DUPA PLAN UN MUNCITOR TREBUE SA FACA 125 DE PIESE. EL A DEPASIT PLANUL, REALIZIND 120%. CITE PIESE A FABRICAT MUNCITORUL
Răspuns:
150 de bucăți
Explicație pas cu pas:
Numărul de piese care ar trebui realizate = 125
Procent realizat = 120%
100% ar fi egal cu numărul de piese care ar trebui realizate;
100% = 125
120% = x
Crucea se înmulțește
100% * x = 120% * 125
x = 150
Prin urmare, numărul de piese realizate este de 150 de piese.

1.9x = 114
x = 114/1.9 = 60
There were 60 members last summer.

Find the equation of a parabola with focus F(-3, 9) and directrix x = -13.
Answer:
y² = 38x + 79
Step-by-step explanation:
Since directrix is the line x = -13, then it means x + 13 = 0
Focus is F(-3, 9).
Let A(x, y) be any point inside the plane having the focus and directrix.
Let MA be the perpendicular distance from A to the directrix and it means that A lies on parabola provided FA = MA.
Thus;
√[(x - (-3))² + (y - 9)²] = (x + 13)
Squaring both sides gives;
(x + 3)² + (y - 9)² = (x + 13)²
>> (x² + 6x + 9) + (y² - 18x + 81) = x² + 26x + 169
>> 6x + 9 + y² - 18x + 81 = 26x + 169
>> y² = 26x + 12x + 169 - 90
>> y² = 38x + 79

Por favor!! Es urgente doy corona plis La edad de Pedro es tres veces la edad de Jorge, la suma de ambas edades es 72 años. Halle ambas edades.
Answer:
Pedro age = 54 ; Jorge age = 18
Step-by-step explanation:
Pedro age = P
Jorge age = J
3J = P
J + P = 72
we have to substitute the value of P in the second equation
J + 3J = 72
we have solve the equation
4J = 72
J = 18
we have to subistute this value in the first equation
3*18 = P
P = 54

To calculate the area of the sector in the circle, π(10 in)² 37 over 360 could be used.
What is the sector of a circle?"It is a part of the circle that is enclosed by two radii and the intercepted arc."
What is the area of the sector of the circle?The formula for the area of the sector of a circle is A = Ф/360° × (π × r²) where 'r' is the radius of the circle.
For given example,
Circle A is shown with a central angle marked 37 degrees and the radius marked 10 inches.
⇒ r = 10 in.
⇒ Ф = 37°
Using the formula of the area of the sector in the circle,
⇒A = Ф/360° × (π × r²)
⇒A = 37/360 × (π × 10²)
⇒ A = π × (10in)² × 37° over 360°
Therefore, the expression used to calculate the area of the sector in the circle is π × (10in)² × 37° over 360°

measure of the central angle?
Answer:
3
Step-by-step explanation:
Radian= arc/radius
18/6=3
The Central angle was calculated to be 3 radians using the formula.
what is a central angle?it is the angle subtended by radii and corresponding arc.
as we know that
length of an arc= central angle* radius
so, central angle = arc length/radius
it is given that
length of the arc=18cm
the radius of the circle=6cm
central angle= 18/6 = 3 radian.
therefore, the central angle was calculated to be 3 radians using the formula.

Write the equation for the word problem and solve. You bought a magazine for $5 and four erasers. You spent a total of $25. How much did each eraser cost?
Answer: each eraser cost 5 dollors
Step-by-step explanation: Simplifying
25 = 5 + 4e
Solving
25 = 5 + 4e
Solving for variable 'e'.
Move all terms containing e to the left, all other terms to the right.
Add '-4e' to each side of the equation.
25 + -4e = 5 + 4e + -4e
Combine like terms: 4e + -4e = 0
25 + -4e = 5 + 0
25 + -4e = 5
Add '-25' to each side of the equation.
25 + -25 + -4e = 5 + -25
Combine like terms: 25 + -25 = 0
0 + -4e = 5 + -25
-4e = 5 + -25
Combine like terms: 5 + -25 = -20
-4e = -20
Divide each side by '-4'.
e = 5
Simplifying
e = 5

The amount of time Mary spends on the phone each month can be thought of as a random variable that is approximately normally distributed. Mary spends an average of 40 hours on her phone with a standard deviation of 4 hours. Find the probability that Mary spends between 30 and 40 hours on the phone.
Answer:
0.4938
Step-by-step explanation:
Given that:
Mean, m = 40
Standard deviation, s = 4
Probability of spending between 30and 40 hours on phone :
Zscore = (x - mean) / standard deviation
P(Z = 40) - P(Z= 30)
((40 - 40) / 4) - ((30-40) / 4)
(0/ 4) - (-10/ 4)
P(Z < 0) - P(Z <-2.5)
P(Z^ 0).=0.5 ; P(Z < - 2.5) = 0.0062097
0.5 - 0.0062097
P = 0.4938
